I've just signed up for MTD and have received my confirmation email from HMRC. Signed in to MTS through QB, granted permissions etc. All seemed fine.

Started to do my return but after the first MTD screen I have three returns ready, all showing zero and they are all 3 previous returns and no current one to file. Which is ready with no errors.

Just to see what would happen I hit file vat with the last quarter selected but it just fires up a load of HTML code in one of the windows so looks like there's a QB issue somewhere. See attached screenshot.

I'm now stuck with no method of filing my VAT.

Please advise.
